Thanks for taking the time to report this bug. > First of all, I want to build a system for production in wich I can build > (very) fast new VM's. > I installed Ubuntu Server 10.04.2 64Bit as host OS with the following > partitions: > > /Boot [Prim] 1GB (EXT4) > / [Prim] 25GB (EXT4) > swap [Prim] 25GB (swap) > ---extended--- > /tmp [Logical] 25GB (EXT4) > /var/log [Logical] 10GB (EXT4) > lvm [Logical] 1,5TB (lvm) > > When I use VMBuilder and build to a RAW logica volume (lvm), it takes more > than 12 minutes! I'd recommend building a single pristine image (where time to build doesn't matter), and snapshot or copy that when you need a new image and make the few changes you need to. Maybe that was your plan all along, but since you mention the time it took to make the first image, I wasn't sure. > Then I tried to change the /tmp partition (of the HOST) to EXT3 and it did take less than 4 minutes!!!! Interesting. Are you using a local archive mirror? It's possible that if you switch back to ext4 now it'll go much faster. > The only problem now is that the VM gives the following error on startup: > EXT4-fs error (device sda1): ext4_mb_generate_buddy: > EXT4-fs group 2: 3431 blocks in bitmap, 3597 in gd > > Any ideas? Is sda1 your tmpfs? If so, edit your fstab to mark it as ext3. > Maybe first any ideas for a workaround? Actually long-term for most image building we recommend switching to live-build. If you try that, and your host has enough memory (more than 4G), then building out of a tmpfs can make for very fast, 2-4 minute, image builds.
